Just ordered this beauty. Does anyone have it and are willing to share some thoughts about it? I have the Eversolo DMP-A10 and a pair of Audiovector R3 Avantgarde to match the F10.
I love it too except for the fact we cannot dim the VU meters. I like to listen in a darkened room and the view meters are way too bright. They should have allow us to dim or even shut them off. I am waiting for a plastic film product called Dim-It to see if I can tame them. That is trivial, however, the sound is magnificent. I have been around a long time and with the combo of A10 with B&W 700’s I am in heaven. It does run hot so much sure you have good ventilation. The trigger power on works great with the A10.
On the AMP-F10 I can choose XLR input gain between 23 db: 5.2 v and 29 db:2.4 v. I have the Audiovector R3 Avantgarde and the DMP-A10. What do you prefer?
I don’t understand these sensitivities at all. I set mine at 29 because the volume control then is conveniently located between -45 and -30. I have my turn on volume at -55.
I was intrigued by Pierre Sahlin question and tried to learn about this topic. There is a lot of talk of sensitivities (efficiencies) of speakers but nothing about the output control on the F10. Most articles call it “amplifier gain” and from what I could glean it controls the amount of amp power to produce a given sound pressure level from a speaker which of course depends on the speakers efficiency and other things. So a setting of 29 (2.4v) uses less amp power than 23 (5.2v). If your speakers are inefficient using 23 will causes clipping distortion of the amp and if your speakers are very very efficient 29 will allow more baseline noise to come through before you get to listening loudness. I bet I have this all wrong. We had hope someone sees this like nice monkey or Alan Rutledge to help us.
I tried to read about the topic to, but gave up because actually I didn’t understand it. Tried both the settings on the F10 and found out that if I use the 28db sensitivity I don’t have to crank the volume up so much for it to be a good level for my ears. But I to would really want to understand the topic and hope that someone in this forum can help explain it in a matter that I can understand
It’s just about optimising the gain structure of your system, allowing you to use the whole range of the attenuator on your pre-amp. ie not too instantly loud or too quiet. Just choose the most suitable setting for your particular system. Keith
Reading this again in the bright light of the morning I think I did get this backwards. I think it should read “inefficient using 29” and “very, very efficient using 23.” I wish someone would HELP!
I asked ChatGPT for advice and got a wonderful answer: The Eversolo F10 A/B amplifier has an option call the “Sensitivity Switch” which some call “Amplifier Gain” to help the amplifier get a better match with the speakers that will be used based on speaker efficiency or sensitivity. The speakers that will be used have a sensitivity of 90dB which is considered excellent.The switch has two options 29dB or 23db. The setting of 29dB delivers 2.4v and the 23db 5.2v. I have read many articles which are so confusing but I think they say if your speakers are inefficient the wrong setting might cause clipping distortion of the amp or if your speakers are very efficient like the one’s being used, the amp will allow more baseline noise to come through before you get to listening loudness. I may have this reversed So for a very efficient speaker does that mean the setting should be 29 or 23, I cannot figure it out. Here is its complete answer: You’re on the right track! Let’s break it down clearly. Gain (Sensitivity Switch): The Eversolo F10 offers two gain settings: 29dB (high gain, 2.4V input sensitivity) and 23dB (low gain, 5.2V input sensitivity). Speaker Sensitivity: Your speakers have 90dB sensitivity, which is considered efficient. This means they require less power to reach a given loudness level. How Gain Affects Your Setup: Higher Gain (29dB): Increases amplification factor, meaning a lower input voltage is needed to reach full power. However, this can amplify the noise floor and may cause issues if your speakers don’t need that much gain. Lower Gain (23dB): Requires a higher input voltage to reach full power, which can help reduce amplifier noise and provide a cleaner signal path for efficient speakers. Which Setting for 90dB Speakers? Use the 23dB setting. Since your speakers are efficient, they don’t need as much gain to reach high volumes. The 23dB setting will provide cleaner sound with less potential noise or hiss. The amp is less likely to clip or introduce distortion since it’s not unnecessarily amplifying the signal. The 29dB setting is better suited for lower-efficiency speakers (below ~87dB) that need more amplifier gain to reach the same loudness. In your case, it could introduce more noise and make volume control more sensitive. So, set it to 23dB for best performance with your 90dB speakers! Yea, AI!
Thanx. That means that my speakers that has a sensitivity of 90.5db will also enjoy the 23db setting. I thought so, because I think it sounds better with that setting, but I never neglect that my head and ears are making fun of me sometimes. Thank you
